摘要:
A hydrogen gas supply device supplies hydrogen gas to a fuel cell stack and includes an electromagnetic pressure regulating valve that regulates the pressure of the hydrogen gas to low pressure. The electromagnetic pressure regulating valve includes a housing, and a valve passage connecting a primary port and a secondary port is formed in the housing. A valve body controls an opening degree of the valve passage and is provided in the housing. A high-pressure sealing member and low-pressure sealing member are provided on an outer periphery of the valve body. The high-pressure sealing member and the low-pressure sealing member are provided in this order from one end side of the valve body to the other end side thereof. The electromagnetic pressure regulating valve further includes a housing pressure equalizing passage connecting the secondary port and a buffer chamber formed between the high-pressure sealing member and the low-pressure sealing member.

摘要:
In a reforming reactor (31), a partial oxidation reaction is performed between a hydrocarbon fuel and air, and in a mixer (32), water is injected into hot gas heated by the partial oxidation reaction to vaporize the water, and the vaporized water is mixed with the hot gas. In a shift reactor (33), the vaporized water is made to undergo a shift reaction with the hot gas. In this way, a device for promoting vaporization of the water or a complex fuel injection device is not required.

To obtain stable linear torque-output characteristics over a wide torque range in a magnetostrictive torque detecting apparatus having a shaft to be measured, an exciting coil for magnetically exciting the shaft, and a detecting coil for detecting magnetostrictive components generated in the shaft distorted by a torque, the shaft is particularly composed of a substrate shaft portion made of a high yield point material and a shape anisotropic layer portion made of a high magnetostrictive material metallographically welded on an outer surface of the substrate shaft. The welded shape anisotropic layer portion is formed with two symmetrical groups of concave/convex portions each arranged at regular angular intervals on the outer circumferential surface thereof at an inclination angle with respect to the axial direction of the shaft.

摘要:
An acrylic resin composition comprises an organic silicon based compound that can be copolymerised with or mixed with acryl monomer or methacryl monomer in the acrylic resin. The acrylic resin composition may contain inorganic fine grains of which the hydroxyl group or the methyl group is bonded to their surface. A painted-film molded resin plate and a coating member for a solar cell panel use the above acrylic resin composition.
